Reason:

There is a gateway validation process that checks for outbound connectivity during start up. This validation test was trying an outbound socket connectivity check without passing through the proxy and failing.

Solution:

Fixed in SmartSense 1.4.0. Please upgrade to this version and restart Gateway to automatically fix the issue. Gateway supports backward compatibility where HST 1.2.x or HST 1.3.x can use the Gateway 1.4.0 to upload bundles. Otherwise, for 1.3.x set the property in /etc/hst/conf/hst-gateway.ini in gateway section and restart Gateway:

start.validation.enabled=false
